Abstract

The present invention relates to a multi-functional juicer which selectively provides a mixer function for grinding content through high-speed rotation of a screw and a juicer function for compressing content through low-speed rotation. According to the present invention, since a mixer and a juicer do not need to be separately provided, the multi-functional juicer is economical and efficient. As the rpm of the screw therein is controlled through a detachable transmission module, the volume occupied by the device may be reduced, and space may be more efficiently utilized.

Description

MULTI-FUNCTIONAL JUICER INCLUDING TRANSMISSION MODULE
The present invention relates to a multi-functional juicer having a controllable speed, and more particularly, to a multi-functional juicer which is capable of concurrently providing a mixer function through high-speed rotation and a juicer function through low-speed rotation.
Conventional juicers hold fruits or vegetables in a housing thereof, in which a grinding screw is rotatably mounted, and rotate the grinding screw using a driving unit positioned at the bottom of the housing, thereby grinding the fruits or vegetables. Then, a user removes and uses the ground fruits or vegetables.
The conventional juicers have an advantage in that grinding is performed within a short period of time, because their content are finely ground by the grinding screw driven at high speed. However, since fruits or vegetables are ground at high speed by the grinding screw, the unique taste and nutrients of the fruits or vegetables may be destroyed. That is, conventional juicers have a limitation in that the user is prevented from fully enjoying the unique taste of fresh beans or fruits, and that nutrients required for health may be lost.
Recently, much attention has been paid to a juicer 5 which reduces rotation speed and increases rotation torque, to thereby solve the above-described problem, as illustrated in FIG. 1. The juicer 5 employs a juice extraction method of squeezing fruits or vegetables into juice while rotating the grinding screw 30 at low speed. Such a method requires a considerably large force, in order to still squeeze fruit or vegetable into juice while reducing the rotating speed of the grinding screw. Thus, the juicer 5 squeezes the fruit through a gear formed in a rotating body.
However, the efficiency of this technique inevitably decreases as the juicer 5 must maintain a constant number of rotations regardless of the content of the juicer. Furthermore, when a large load must be processed by the grinding screw of the juicer operating at low speed, for example, when a solid or dense vegetable such as a carrot is processed, the driving unit may become congested and caused to stop functioning. In this case, the user must remove the source of congestion in the driving unit and restart the juicer, which is an inconvenience for the user.
Therefore, the inventors of the present invention have conceived a multi-functional juicer which includes a detachable variable module mounted thereon so as to provide a mixer function for grinding content and a juicer function for compressing content, in the course of conducting research on a juicer in which functionality may modified according to content in the juicer or the user's needs.
An embodiment of the present invention is directed to a multi-functional juicer including a mixer function for grinding content at high speed and a juicer function for compressing content at low speed.

When the driving unit 200 and the transmission module 400 are connected to each other, the rotations per minute (rpm) of the screw 300 may decrease.
The transmission module 400 may be positioned between the driving unit 200 and the screw 300.
The transmission module 400 maycomprise: a first sun gear 421 connected to the shaft of the driving unit 200; one or more first planet gears 422 engaged with the first sun gear 421; a first ring gear 426 engaged with the one or more first planet gears 422; a second sun gear 461 having the same shaft as the first sun gear 421; one or more second planet gears 462 engaged with the second sun gear 461; one or more third planet gears 440 engaged with the one or more second planet gears 462; and a second ring gear 466 engaged with the one or more third planet gears 440, and rotating shafts of the one or more second planet gears 462 and the one or more third planet gears 440 which may be inserted into one or more insertion grooves 428 positioned at an upper surface 427 of the first ring gear 426.

2. Descriptions for operation of the juicer according to the embodiment of the present invention
The juicer 50 according to the present invention may perform various operations (mixing, juicing, kneading and the like). However, the following descriptions will be focused on the operation of the juicer 50 which provides a mixer function and a juicer function.
When a user wants to grind solid content or finely grind food, the user may select a mixer function. In this case, the driving unit 200 may be rotated at high speed.
At that time, the transmission module 400 of the juicer 50 may be not operated, or may not be mounted as illustrated in FIG. 2b.
Among the plurality of screws 300, the mixer screw 310 illustrated in FIG. 2a is selected and mounted in the upper housing 120.
The driving unit 200 is rotated at a high speed of about 3,000 to 4,000 rpm. The mixer screw 310 includes a sharp grinding blade suitable for grinding, and finely grinds content through the high-speed rotation of the driving unit 200.
When a user wants to drink fruit juice having preserved nutrients, the user may rotate the driving unit 200 at low speed. In this case, the transmission module 400 is connected between the driving unit 200 and the upper housing 120. Furthermore, among the plurality of screws 300, the juicer screw 320 suitable for squeezing or compressing is mounted in the upper housing 120 as illustrated in FIG. 2b.
The screw 320 connected to the shaft 305 of the driving unit 200 connected to the transmission module 400 is rotated at a low speed of 50 to 100rpm. As illustrated in FIG. 2b, the juicer screw 320 has a reverse-circular-cone shape suitable for compression, and includes a screw-type grinding blade provided on the surface thereof. Thus, according to a user's request, the juicer 50 may provide squeezed juice of content deposited thereto.
The operation of the transmission module 400 according to the present invention will now be described.
The rotating force from the driving unit 200 is transmitted to the first and second sun gears 421 and 461. Thus, the first sun gear 421 is rotated in the same direction as the second sun gear 461.
The operation of the transmission module 400 according to the embodiment of the present invention will now be described.
The one or more first planet gears 422 are rotated through the rotation of the first sun gear 421, and the first ring gear 426 is rotated through the rotation of the one or more first planet gears 422.
The one or more second planet gears 462 are rotated through the rotation of the second sun gear 461, the one or more third planet gears 440 are rotated through the rotation of the one or more second planet gears 462, and the second ring gear 466 is rotated through the rotation of the one or more third planet gears 440.
As the first ring gear 426 is rotated, the one or more second planet gears 462 and the one or more third planet gears 440, of which the rotating shafts are inserted into the insertion grooves 428 positioned at the upper surface 427 of the first ring gear 426, revolve around the second sun gear 461.
Simultaneously, the one or more second planet gears 462 and the one or more third planet gears 440 are rotated around the rotating shafts thereof through the rotation of the second sun gear 461.
The first sun gear 421 is rotated in the opposite direction of the first ring gear 440 by the one or more first planet gears 422. Furthermore, the second sun gear 461 is rotated in the same direction as the second ring gear 466 by the one or more second planet gears 462 and the one or more third planet gears 440.
Since the first and second sun gears 421 and 461 are rotated in the same direction, the first ring gear 426 is rotated in the opposite direction of the second ring gear 466. Thus, the one or more second planet gears 462 and the one or more third planet gears 440, of which the rotating shafts are inserted into the one or more insertion grooves 428 of the first ring gear 426, revolve around the second sun gear 461 in the opposite direction to the rotation direction of the second ring gear 466. That is, since the one or more second planet gears 462 and the one or more third planet gears 440 transmit a rotating force to the second ring gear 466 while revolving in the opposite direction to the rotation direction of the second ring gear 466, the rotation speed is further reduced than before.
The operation of the transmission module 400 according to another embodiment of the present invention will now be described.
The one or more first planet gears 422 are rotated through the rotation of the first sun gear 421, the one or more third planet gears 440 are rotated through the rotation of the one or more first planet gears 422, and the first ring gear 426 is rotated through the rotation of the one or more third planet gears 440.
The one or more second planet gears 462 are rotated through the rotation of the second sun gear 461, and the second ring gear 466 is rotated through the rotation of the one or more second planet gears 462.
As the first ring gear 426 is rotated, the one or more second planet gears 462 of which the rotating shafts are inserted into the one or more insertion grooves 428 positioned at the upper surface 427 of the first ring gear 426 also revolve around the second sun gear 461.
Simultaneously, the one or more second planet gears 462 are rotated around the rotating shafts thereof through the rotation of the second sun gear 461.
The second sun gear 461 is rotated in the opposite direction of the second ring gear 466 by the one or more second planet gears 462. Furthermore, the first sun gear 421 is rotated in the same direction as the first ring gear 426 by the one or first planet gears 422 and the one or more third planet gears 440.
Since the first and second sun gears 421 and 461 are rotated in the same direction, the first ring gear 426 is rotated in the opposite direction of the second ring gear 466. Thus, the one or more second planet gears 462 of which the rotating shafts are inserted into the one or more insertion grooves 428 at the upper surface 427 of the first ring gear 426 are revolved around the second sun gear 461 in the opposite direction to the rotation direction of the second ring gear 466. That is, while the one or more second planet gears 462 revolve in the opposite direction to the rotation direction of the second ring gear 466, the one or more second planet gears 462 transmit a rotating force to the second ring gear 466. Thus, the rotating speed is reduced further than before.
The juicer 50 according to the embodiment of the present invention is not limited to the above-described operation, but may be operated in response to a user's needs, according to the rpm resulting from the selected screw 300 and whether or not the transmission module 400 is mounted.
